Financial self-service device and anti-peeping system and anti-peeping method thereof

Abstract

The invention provides an anti-peeping system, which is applied to a financial self-service device. The anti-peeping system comprises an image acquiring and processing module, an anomaly detection module and an alarm module. The image acquiring and processing module comprises an image acquiring controller, at least a pair of image sensors and an image processing unit and is used for acquiring original image data and rebuilding three dimension so as to acquire distance information of each image relative to the financial self-service device. The anomaly detection module comprises a human-face detection unit and a view angle calculation unit and is used for detecting whether multiple human faces exist or not and calculating a view angle range watched by human eyes so as to judge whether the human faces watch an operation panel or a display screen. The alarm module is used for conducting response to detection results of the anomaly detection module so as to warn whether current customers are peeped or not. By means of the scheme, the accuracy rate of judging peepers can be improved greatly, and the misinformation rate of an alarm is reduced.

Description

technical field [0001] The invention relates to a financial self-service device, in particular to an anti-peeping system and a method for peep detection and alarm of the financial self-service device. Background technique [0002] With the rapid development of my country's economy, the circulation of banknotes is increasing, and self-service terminal equipment has become the main way for modern commercial banks to provide services to users. With the wide application of self-service terminal equipment, self-service terminal security issues have become increasingly prominent, especially around security issues around financial self-service equipment, such as peeking at passwords and secretly changing cards. For the security issues around the financial self-service equipment, the existing preventive measures mainly include anti-peeping mirrors and safety islands based on physical isolation. [0003] Patent 20090214311.7 proposes a financial self-service terminal and its securit...

Problems solved by technology

[0004] However, the security protection technology based on face detection is to use the camera installed on the financial self-service equipment to judge the face. If there are multiple faces, according to the positional relationship between the faces, it is judged whether there is a peeping event. In this way False positives are prone to occur, causing unnecessary tension for trading clients

For example, when someone passes behind the trader and the face information is captured by the camera, false alarms will occur; when multiple ATMs are placed side by side, due to the large number of transactions, queuing will occur, and the camera of the ATM may display Normal queuing personnel (who did not peek at the screen) were mistaken for voyeurs, resulting in false positives
